How can I disable SEF for some components? for example I would disable SEF-rewrite to my aritcle section and category because joomsef show 404 error for some links.

For example this article is working good: www.mysite.com/section-name/article-title

but I can't load a category page: www.mysite.com/section-name/ (404 error)... When I disable joomsef plugin it is loading fine...

How can I fix this 404 error to load article list of my section without problems?

Hello,

It is not possible to disable SEF for only some parts of the component. You could only disable SEF for whole Content component.

As regards the error - does it show the Not found message in the Joomla template, or is it a standard 404 Not found error in the web browser?
Make sure the "Be tolerant to trailing slash" option is enabled in JoomSEF's configuration on Advanced tab.

Best regards,
ARTIO Support Team

The error is: 404 - Article not found: #3571
but the URL is to my Article Section List (all article from one of my section).
I think the SEF don't know about this section - because I don't see in Manage SEF url TABs.

Yes I have enable "be tolerant to trailing slashing".
How can I fix this?

Try clearing the JoomSEF's cache using the button in JoomSEF's control panel.
